| 中文摘要: |
| 针对机械产品制造检测过程中质量特性之间存在相关性以及检测效率低的问题，以实现高效、准确关键质量特性（key quality characteristics，KQCs）识别为目标，提出了基于熵权法(entropy weight method)和马氏田口法（Mahalanbis Taguchi system method，MTS）的识别方法。在介绍产品设计阶段以及制造过程关键质量特性研究的基础上，分析了熵权法中熵值熵权的获取，以及马氏田口法中马氏距离和田口方法在质量特性识别中的应用，提出了两种模型结合识别机械产品关键质量特性的方法。以六轴五联动机床的皮带传动轴为例介绍了该方法的应用。结果表明该方法能有效处理质量特性之间的相关性问题，提高KQCs识别效率。 |

| Aiming at the problem of low detection efficiency and correlation between quality characteristics of mechanical manufacturing in the process of detection, a recognition method based on entropy weight method and MTS (Mahalanobis Taguchi system method) was put forward under the target of achieving efficient and accurate identification. Based on the introduction of key quality characteristics in the product design stage and manufacturing process, the acquisition of entropy was analyzed. Then the application of Markov distance and Taguchi method of Mahalanbis Taguchi system were proposed. The process of identifying the key quality characteristics of mechanical products with these two modes was presented. The application of this method was introduced by taking the belt drive shaft of six axis five linkage machine tool as an example. The result shows that the method can effectively solve the correlation between quality characteristics, and improve the efficiency of KQCs identification. |
